Systemic vascular resistance

The outlet resistance blood meets as it flows through systemic vessels.

これは何か

Systemic vascular resistance is the resistance blood meets across the systemic circulation, strongly shaped by small arteries and arterioles.[1]

なぜ重要か

When resistance is higher, the same flow needs more pressure to pass through the vascular system.[2,1]

異常値が生じる根本原因

  • Core relation: Narrower systemic vessels create more outlet resistance; more resistance means blood flow needs a higher pressure gradient to move through tissues.[1,2]

どの判断に影響するか

  • It is a bridge between vessel tone, blood pressure, afterload, and perfusion context.[1]

解釈上の注意

  • BioConst does not estimate personal SVR from routine blood pressure readings.[1]
